New Organ Build Topsy 3

Thanks Ted. I'll check that out. I know that the ones I have on my VWs are not like yours.

unless vw does something really different they all work the same. If you open up the gearbox it should be similar

Hey Folks I ran into another problem today on the bass plate on the bottom of the main windchest the drawing on pg #11 says the holes are 3/4 form the edge but the pallet magnets will not fit at that dimension I went to 1" and it seem to work the plate also will need to be more than 3 1/8 as shown. I'm using 3 1/2 and will let you know it there is a problem. I may get by with narrower but will have to use the pallet magnets from Organ Supply instead of the Peterson for the Bass pipes as they are shorter per there catalog.

Ted, I was referring to my "old" 1971 and 73 Karmann Ghias. That's what I have in storage. I'll check one out though.

On another front, John talks of using "twin thread" screws for assembling the organs. Has anyone found any in the US? Tried Google, after page after page of UK sites, I quit looking. Hardware stores around here never heard of them. What screws are you all using?

[ted heid]

regular screws worked fine for me

[Jay Caughron]

That's all I use also. Any good wood screw is fine I use a lot of #4 #5 and some #6 screws.
Is this something I need to stock on my web site??

[Harold Whipps]

In my search for the twin thread screws, when I looked at some of their pictures, they looked like they would grip a lot better. Very good looking screws. As to stocking them for your site, I think you would need to try and find some and test them before making that decision.

I don't know if they are cut threads or rolled threads. I have been told that rolled threads are stronger, but how do you know which is which? I'll keep looking.

Found some interesting info on screw use. Small doc file attached if I did it right.

[ted heid]

I don't see any info on mitering the accompaniment pipes. Is the "A" 90 done like the counter melody pipes with the 1/2 inch narrow bend, "B" looks to just be a 45 but at what length do you cut? A might be just to keep it under the top lid but no guess on B. Can you cut these with a miter saw or would the blade chew the pipes up?

[Jay Caughron]

Yes you can cut them with a miter saw. That's what I use but you want to cut slow got to fast and it will splinter. A little bit wont hurt but try for as clean a cut as you can. I just use a combo blade on mine with 60 teeth.

Not sure on the angles yet I haven't got to that point but it will probably just have to be made to fit in your case. There are some of the country melody pipe on the outside edge of the case that are more than 90 so the point down away from the top.
